DoubleStar Receiver Extension Buffer Tube 6-Position Mil-Spec Diameter AR-15, LR-308 Carbine Aluminum Matte
NOTE: This buffer tube has a slightly angled rear end that resembles a commercial diameter buffer tube, however the outside diameter of the DoubleStar tube does indeed adhere to the Mil Spec diameter. The angled rear surface may interfere with some aftermarket buttstocks by not allowing the stock to engage the first position (fully collapsed) on the tube.
